Abstract
Purpose of review
Amyotrophic lateral sclerosis (ALS) is a severe disease characterized by the degeneration of motor neurons. Large-scale genetic studies have now identified over 60 genes that are associated with ALS, which in large part have also been functionally characterized. The purpose of this review is to outline how these advances are being translated into novel therapeutic strategies.
Recent findings
The emergence of techniques that allow the specific therapeutic targeting of a (mutant) gene, in particular antisense oligonucleotide therapy (ASOs), have led to the first successful gene therapy for SOD1-ALS and multiple other gene-targeted trials are underway. This includes genetic variants that modify the disease phenotype as well as causal mutations.
Summary
Technological and methodological advances are enabling researchers to unravel the genetics of ALS. Both causal mutations and genetic modifiers are viable therapeutic targets. By performing natural history studies, the phenotype-genotype correlations can be characterized. In conjunction with biomarkers for target engagement and international collaboration, this makes performing gene-targeted trials ALS feasible. The first effective treatment has now been developed for SOD1-ALS and, with multiple studies underway, it seems realistic that more therapies will follow.
